Bulgaria Population 2026: The European Country Losing Population Faster Than Any Other
When Bulgarians elected their first post communist government in 1990, the country had a population of approximately 8.99 million. Thirty-six years later, the Bulgarian population in 2026 stands at approximately 6.5 million, according to the live counters on worldpopulationclock.net drawing on the United Nations World Population Prospects 2024 revision and the National Statistical Institute. The cumulative loss exceeds 2.5 million people, or roughly 28 percent of the 1989 population. No other country in the European Union has lost a comparable share of its population in the modern era, and few countries anywhere have experienced peacetime population declines of this magnitude.
The decline reflects the convergence of multiple demographic pressures: low fertility well below replacement, elevated mortality and limited life expectancy improvements, and most importantly, sustained emigration of working-age Bulgarians to Western European countries that has compounded across decades. Bulgaria provides perhaps the clearest case study of what happens when fertility decline, emigration, and aging compound without significant offsetting forces.
This article examines the Bulgarian population through the lens of the country’s extraordinary decline, the regional distribution across 28 provinces, the demographic forces still operating in 2026, and the projected trajectory toward what could be a population below 5 million within several decades.
A Decline That Has No Modern Peacetime Parallel
Bulgaria’s population peaked in 1988 at approximately 9.01 million, just before the end of the communist period. The decline since has been nearly continuous:
- 1988: 9.01 million (peak)
- 1990: 8.99 million
- 2000: 8.15 million
- 2010: 7.43 million
- 2020: 6.91 million
- 2026: 6.50 million
The cumulative decline of 2.5 million across 36 years averages approximately 70,000 net residents lost per year. The drivers have shifted somewhat across the decades. The 1990s saw the largest fertility collapse, with total fertility falling from approximately 1.95 in 1989 to 1.10 by 1997. The 2000s and 2010s saw the largest emigration episodes, with Bulgarians moving in substantial numbers to Spain, Germany, Italy, the United Kingdom, Greece, and various other destinations.
The 2011 to 2021 census revealed that Bulgaria had lost approximately 845,000 residents over the previous decade, a figure that surprised even pessimistic demographic observers. The 2021 census recorded a population of approximately 6.5 million, down from 7.36 million in 2011.
Bulgaria Population by Province: A Detailed Breakdown
Bulgaria is divided into 28 provinces (oblasts), each named after its principal city. The provincial distribution reflects centuries of settlement and the more recent geography of decline.

Sofia City holds approximately 1.27 million residents and continues to attract internal migrants even as Bulgaria overall loses population. The Sofia metropolitan area approaches 1.6 million when surrounding suburban areas are included. Plovdiv, at 645,000, is the second largest province by population.
The provinces along the Black Sea coast (Varna and Burgas) have grown through tourism, retirement migration (including significant numbers of British and other Western European retirees who purchased Bulgarian property in the 2000s), and modest economic dynamism. Most other provinces have lost population substantially over the past two decades.
Vidin Province in the northwest holds only approximately 70,000 residents and has lost more than half of its population since 1989, ranking among the most depopulated administrative units in Europe. Several other northwestern provinces have experienced similarly steep declines.
Demographic Profile in 2026
Bulgarian total fertility sits at approximately 1.65 children per woman in 2026, slightly above some Central European peers but well below the 2.1 replacement threshold. Fertility has recovered modestly from the 1.10 low of 1997.
Median age in Bulgaria sits at approximately 45 years in 2026, among the oldest in the European Union. Approximately 22 percent of Bulgarian residents are aged 65 or older, with the share projected to climb past 30 percent by 2050.
Life expectancy at birth in Bulgaria stands at approximately 75 years overall, with women averaging approximately 78 years and men approximately 71 years. Bulgarian life expectancy lags Western European peers by approximately 7 years, reflecting persistent challenges around cardiovascular disease, healthcare access in rural areas, and lifestyle factors.
The Bulgarian Roma community numbers approximately 325,000 to 500,000, depending on self-identification methods, accounting for approximately 5 to 8 percent of the population. Roma fertility is higher than the national average, contributing to slower aging in Roma majority districts.
The Bulgarian Emigration
The Bulgarian diaspora abroad numbered approximately 2 million in 2026, nearly one-third of the home country population. Major destinations include:
- Spain: approximately 200,000
- Germany: approximately 410,000
- United Kingdom: approximately 165,000
- Italy: approximately 100,000
- Greece: approximately 75,000
- United States: approximately 75,000
- Turkey: approximately 380,000 (largely ethnic Turkish Bulgarians)
- Various other EU destinations and beyond
The 1989 expulsion of ethnic Turkish Bulgarians by the communist government, followed by their partial return after 1989 and continued back-and-forth migration, has created a particular pattern of Bulgarian Turkish migration to Turkey. Post 2007 EU accession enabled large-scale migration of Bulgarians to Western Europe under freedom of movement provisions.
Future Projections
| Year | Projected Bulgaria Population | Notes |
|---|---|---|
| 2030 | 6.35 million | Continued decline |
| 2040 | 6.0 million | Aging accelerates |
| 2050 | 5.6 million | Loss of 900,000 from 2026 |
| 2075 | Loss of more than half from the 1988 peak | Continued steady decline |
| 2100 | 4.4 million | Loss of more than half from 1988 peak |

The Bulgarian population 2100 figure of approximately 4.4 million implies a cumulative decline of more than 50 percent from the 1988 peak. The projection assumes no major reversal of emigration patterns or fertility trends, which has been the consistent reality for over three decades.
Projections from the UN World Population Prospects 2024 revision suggest the Bulgarian population will fall to approximately 6.35 million by 2030, around 5.6 million by 2050, and approximately 4.4 million by 2100. The trajectory assumes continued sub-replacement fertility, sustained emigration at moderating rates, and gradual mortality improvements.
